Specification of Letters Patent.

Patented May 12, 1908.

To all whom ttmay concern:

Be it known that we, JOHN H. MARSH and Josnrn J. LANZIT,- citizens ofthe United States of America, residing at Chicago, in the county of Cookand State of Illinois, have invented certain new and useful Improvementsin Cartons, of which the following is a vice 'wheo still furtherwrapped; Fig. 5

shows the device completely closed; and Fig. 6 is a section in the line6-6 of Fig. 5.

Referrin to the drawings, it will be seen that the blank has a longrectangular central portiondivided by score marks into sections, A, A,A, A and, A, the section, A,

referably having its corners cut oil an avin at its free end a smalllockin flap, A. 11 forming our im roved box a out a solid body, as isordinar y done, the body is laid do the section, A, the section, A,being brought up on one side of it, the section, A, lying above it, andthe locking fia A turned down as illustrated in ig. 2. The body is thenrolled over from the position shown in Fig. 2 to the position shown inFig; 3, so as to bring the section, A, on top This lays the section, A,underneath the package, and outside the locking flap, A and thereuponthe section, A, is swung up into a vertical position outside thesection, A. When the parts are in this position, it will be seen that 1the section, A, is absolutely locked against outward movement withrespect to the package, and that it is only b first moving out thesections, A, A, that t c section, A, can be swung away. These sectionsare in practice locked by the end flaps of the package, so as to makeany such movement of the sections, A, A, impossible, and, as a result,the structure is firmly held in osition without the use of glue. Theendv a s referred to consist of two inner flaps, on each end of thepackage, and a single outer .tongue B flap, B, on each end of thepackage, each of the flaps, B, having a short bent end, or In practice,the inner flaps are swung in from opposite sides of each end and are,consequently, placed on alternate sections of the blank, so that whenthe box is folded up, they will lie opposite each other. The outer flapsswing over the inner flaps at right angles thereto, and the bent ends ofthe outer flaps swing in over the edges of the inner flaps, locking themin position. In order to get the best looking effect, we prefer to havethe inner flaps on the sections, A, A of the blank and to have the outerflaps so arranged that when the box iscompleted, one outer flap shallhinge on one edge of the box and the other on the diagonal oppositeedge.

It will be seen that when the end flaps are swung in as illustrated inFig. 4, the sections, A, and A, which operate to hold in the sections,A, and A of the blank are firmly locked down to the package byengagement of the end flaps, the outer flaps at each end embracing theinner flaps on the section, A, and thus reventing, movement thereof.This type oi box can be assembled with ex trerne rapidity and isespecially desirable, and is, in fact, particularly desi ned, for use inwrapping butter, cheese, and the like. When use for this pur ose, thepasteboard will referably be para ed on the inside.

e realize that considerable variation is possible in the details of thisconstruction, and hence do not limit ourselves to the specific formherein shown and described.

We claim as new and desire to secure by Letters Patent 1. In apasteboard box assembled without the use of adhesive and held inposition solel by the interlocking of its parts, the com ination withfive side-sections arran ed in a series, and a locking section at the enof the series and attached integrally to the exflaps being ap roximatelyone-half the combined len th 0 the first-named end-flaps and tongues, orthe 'urpose set forth.

2. In a pasteboard box assembled Without the use of adhesive and held inposition solely by the interlocking of its parts, the combination withfive side-sections arran ed in a series, and a lookin -section at the onof the series and attache integrally to the extreme edge thereof, thesections being'bent to inclose a space rectan ular in cross-section, thefifth section lying lnside the first section and the lockin -sectionlying inside the second section of t 1e series, of an end-flap at oneend of the second section and a corres 0nding end-flap at the op ositeend of the ourth section, each of said end-flaps being. provided With atongue, and an end-section at each end of both the first and thirdside-sections, each of the last-named end-flaps being approximatelyone-half the combined length of the first-named fla s and tongues, eachend-flap being integra with a side-section and each tongue being interal With an endfla for the purpose set fort n Witness whereof We havesigned the above application for Letters Patent, at Chicago, in thecounty of Cook and State of Illinois, this 5th day of September, A. D.1905.
